ESP8266-01 /w 8MBIT flash won't boot and gets hot
Posted: Sat Sep 12, 2015 2:52 pm
Hey guys,
I've got an ESP8266-01 module with an 8 MBit Flash and if I use the bootv1.4 method everything works fine.
But if I use der flash.bin directly and make no use of the bootloader, the module only outputs the standard boot message:
Normally it should then print out the smartconfig data, but it doesn't.
Instead the RX and TX LED's of my FTDI-Controller are both lid up and after a few seconds the board and the board and the Serial Adapter get really hot.
I tried the same thing on a different module with only 4 MBits of flash and everything worked out fine.
Tomorrow I will use a multimeter to meassure the current drawing of the board, which i expect to pretty high.
I hope somebody is able to help me.
Greetings Hendrik
PS: I'm using the espressif SDK v1.3.0
